Embodiment Construction

[0024] exist figure 1 shows a tunnel boring machine 1 having a base frame 2 with a crawler 3 . The boom is indicated at 4 and is guided on the base frame 2 so as to be movable in the machine longitudinal direction corresponding to the double arrow 5 . The boom 4 can be mounted pivotally about a vertical axis 6 by means of a horizontal pivot mechanism not shown further.

[0025]The front section of the boom 4 can be supported pivotally about a horizontal axis 7 by means of a vertical pivot mechanism not further shown. In this way, the boom 4 can be pivoted relative to the base frame 2 both horizontally and vertically. The cutting device 8 is mounted on the boom 4 so as to be rotatable about a pivot axis 9 , wherein a rotary drive (not further shown) drives the cutting device 8 for rotation about the axis 9 . The cutting device 8 has two tool holders 10 and 11 which each have a plurality of cutting tools 12 on their periphery. The following will also be based on image 3 an...

Abstract

The invention relates to a tunneling machine comprising a base frame (2) having a chassis, and a bracket (4) which can be horizontally and vertically swiveled and is provided with a cutting device (8) that has at least one tool support (10, 11). Said tool support is rotatably mounted on the bracket (4) and can be driven so as to rotate and carries a plurality of cutting tools (12) on its circumference. The cutting device (8) comprises at least two parallel disk-shaped tool supports (10, 11) which are rotatably mounted on an end section (13) of the bracket (4) that is located between the tool supports (10, 11) and is at least partially disk-shaped.

Description

technical field [0001] The invention relates to a tunnel boring machine (Streckenvortriebsmaschine) comprising a base frame with a running gear and a horizontally and vertically pivotable boom provided with a cutting device with a rotatably supported At least one tool holder at the cantilever and drivable for rotation, the tool holder carries a plurality of cutting tools at its periphery. [0002] Furthermore, the invention relates to a method for boring a tunnel underground by means of a tunnel boring machine. Background technique [0003] Road boring machines of the type mentioned at the outset are known as part-cut mining machines and are common in at least two different constructions, wherein in both cases the boom is pivotably fixed at each at the rack. In a first embodiment, the grooved roller or the cutting head is rotatably mounted on the boom transversely to the longitudinal axis of the boom, and the grooved roller or cutting head is guided in a vertical direction...
